SPECIFICATIONS
External Power Requirements:
All models are signal-powered. Lighted
versions: 12 or 24 Vdc, depending on model.
Display:
Four active digits (0 to 9999), non-blinking
LCD display; character height of 0.5 inches
(14 mm). Display contrast increases with
increasing ambient light.
Input Valve Voltage:
From pickups, pulsers, shaft encoders, etc.
‹ Minimum signal amplitude: 2.5 Vrms.
‹ Maximum permissible signal: 15 Vrms.
The SPD-100 automatically limits pickup
signals at approximately 10 volts peak-topeak. Input impedance is 100 Ω in series
with a 6 volt Zener diode.
Input Signal Frequency:
Maximum input signal frequency of 20,000
Hz. Lowest frequency range limited by gate
time and corresponding numerical display.
Isolated Circuit:
All circuitry is totally floating, i.e. totally isolated
and insulated from the case and from ground.
Operating Temperature Range:
–5o
F to +175oF (–20o
C to +80oC).
Storage:
–40oF to +195oF (–40oC to +90o
C).
Vibration: MIL STD 810C; Method 514.2;
Curve Q; Procedure V; Modified to 500 Hz
upper limit. 5 Hz to 10 Hz @ 0.2 inches
D.A.; 10 Hz to 18 Hz @ 1.0 g (peak); 18 Hz

Procedure V; Modified to 500 Hz upper limit.
5 Hz to 10 Hz @ 0.2 inches D.A.; 10 Hz to 18
Hz @ 1.0 g (peak); 18 Hz to 57 Hz @ 0.06
inches D.A.; 57 Hz to 500 Hz @ 10 g (peak).
ACCURACY
One rpm resolution; within 0.5% (0.1%
typical at room ambient) under all combined
environmental conditions.
GATE TIME RANGES
SPD-100 Series : field-selectable from 0.26
to 5.7 seconds.
SPD-108 Series: field-selectable from 0.13
to 2.85 seconds.
This accommodates calibrations for an
extremely broad range of corresponding
pulses per second.
MAGNETIC PICKUPS
Dynalco Magnetic Pickups M102 and
M107 are used with the SPD-100 Series in
most applications. Refer to Dynalco
Magnetic Pickup brochure for various types
and characteristics.
For low-speed applications, or to permit
operation with larger gaps, the ultrahigh
sensitivity M142 can be used.
For intrinsically safe applications Dynalco
Controls offers various models, with the M202
and M134 the most frequently used.
